Pyro-phototronic Effect Enhanced Self-Powered Photoresponse in Lead-Free Hybrid Perovskite

Pyro-phototronic effect (PPE) can significantly boost the performance of hybrid perovskite (HPs) photodetectors due to the effective modulation of photogenerated charge carrier separations, transportation, and extraction. However, there are few reports on the application of PPE in lead-free HPs. Herein, a polar lead-free HP (1,3-BMACH)BiBr
